BIM (Building Information Modeling, building information model) technology is proposed by Autodesk company in 2002, has been widely accepted in the industry in the world, can help to integrate building information, and is integrated in a three-dimensional model information database from the design, construction and operation of a building to the end of the whole life cycle of the building, so that personnel of various parties such as design team, construction unit, facility operation department and owner can work cooperatively based on BIM, thereby effectively improving working efficiency, saving resources, reducing cost and realizing sustainable development. In China, the development of BIM technology is still in a starting state, the BIM technology is introduced from 2003 into the engineering construction industry in China, the current BIM standard is mainly formulated for building structure engineering, and in power transmission and transformation engineering, the BIM technology does not have a perfect system.
The Autodesk Revit platform is constructed for BIM, can help a building designer to design, build and maintain a building with better quality and higher energy efficiency, and Revit is one of the most widely used software in the BIM system of the building industry in China. In an Autodesk Revit platform, parameterized components (also called families) are the basis of all building components designed and used in Revit, a Revit family library is a database formed by classifying and archiving a large number of Revit families according to properties such as characteristics, parameters and the like, enterprises or organizations in related industries can accumulate into a set of own unique family libraries along with development and deep of projects, and in subsequent work, family library data can be directly called, and parameters can be modified according to actual conditions, so that the work efficiency can be improved.
According to the invention, the design characteristics of the overhead line in the power transmission and transformation project are considered, the modularized thought and the parameter driving technology are introduced into the overhead line modeling process based on the BIM technology, so that the workload of overhead line modeling can be greatly reduced, the working period is shortened, and the working efficiency is improved.
The tower in the overhead line has different tower types according to different conditions such as voltage class, topography and the like, the tower structure is mainly formed by connecting angle steel through bolts at nodes, and the structures of different towers have similarity and inheritance, so that basic conditions are provided for parameterized modeling of the overhead line.
Therefore, the invention provides a BIM-based overhead line model construction method, which comprises the following steps as shown in fig. 1:
a BIM-based overhead line model construction method comprises the following steps:
S1, respectively carrying out line planning and wire calculation according to a topographic map and design data;
s2, combining a line planning result, and adopting a daohe computing software to carry out tower structure design to obtain a formatted tower computing result;
s3, constructing a pole tower model according to a pole tower calculation result by adopting an Autodesk Revit platform;
S4, combining the lead calculation result, and calling a pre-established parameterized part family library from an Autodesk Revit platform to construct each component model;
s5, positioning and assembling the tower model and each component model to obtain the integral overhead line model.
The specific process of the method is shown in fig. 2, line planning, conducting wire and pole tower calculation are firstly carried out according to design data and a topography, a pole tower model group is designed in a Revit group file according to a calculation result output by a daohe calculation software, a parameterized component group library established in the earlier stage is called to be assembled into parameterized component groups such as a conducting wire group and an insulator string group, finally the parameterized component group and the pole tower model group are positioned and assembled into a line, and then an integral overhead line BIM model is obtained, and then the overhead line BIM model can be transferred to other units for actual construction or visual control of the overhead line.
The invention adopts the daohn computing software to calculate the structure of the pole and the tower, the coordinate file, the section, the length and the like of the pole can be calculated according to the design requirement, the calculation result is output to the full stress calculation book, fig. 3 is a schematic diagram of part of the file in the full stress calculation book in the embodiment, the full stress calculation book file mainly comprises a pole material selecting table, pole material stress data, auxiliary materials and stress material data, and the pole and tower model is constructed by referring to the data in the full stress calculation book in the follow-up modeling.
When a tower model is built, the component quantity of the tower is large, the attributes are more, the existing Revit software is mainly oriented to designing a conventional building, components such as a shaft network, a wall body, doors and windows and the like can be conveniently and rapidly drawn, but the building of the tower model is difficult, because the manual modeling needs to position the rod pieces one by one and add the attributes one by one, and the workload is large, the invention performs secondary development on the basis of Revit to simplify the modeling:
The invention uses Visual Studio software and C# language programming, if the Revit API function is called in the program, the function and class provided in the Revit API and RevitAPIUI.dll are required to be called in the program, according to the method, the rod coordinate file and full stress calculation book file output by the Taheng calculation software can be stored in the rod class, then the function in the API is called to read the rod, the rod model can be constructed, the function for generating diagonal bracing members in the called function can be generated in any space, the function for generating diagonal bracing can read the coordinates of two points at any position and the rod information, then the rod model can be generated, after the rod generation is finished, the rod model can be obtained, and the schematic diagram of the rod model of the strain tower and the tower model in the embodiment can be obtained after the rod generation is finished, as shown in fig. 4 and 5.
When building a component model, the family libraries provided by Revit are less related to power transmission and transformation engineering and lack insulator strings and other component family libraries, so the invention automatically builds the component family libraries in Revit according to the types of the components and the corresponding outline detail parts. Taking an insulator string as an example, the component category and the detail parts of the insulator string are shown in table 1:
TABLE 1
Therefore, by combining the related information of other components, the invention establishes a parameterized component group library comprising a screw group, a hanging ring group, an aluminum strap, a right-angle hanging plate group, a UB hanging plate group and a hanging wire clamp group in Revit, and then assembles each component in the parameterized component group library according to the design requirement, thereby obtaining a component model comprising a wire group, an insulator chain group and a hanging wire clamp group.
In summary, the invention provides a parameterized modeling method for the overhead line after dividing the modules (towers and components) based on BIM technology, so as to establish parameterized models of all the modules, and in practical application, the models can be automatically established by only importing formatted modeling text information, thereby reducing modeling workload and having the advantages of high accuracy and good universality.
